Hi,
I want to know which one is better than NetDim(Coalesce Adaptive) in driver.
I know Heng Qi's work in this.
Thanks
Why choose? we can have both.
ethtool can handle both pkt_rate_low/pkt_rate_high and
use_adaptive_rx_coalesce/use_adaptive_tx_coalesce.
The adaptive algorithm can even use this feature to set low and high
coalescing sets.
Hi, all.
NetDIM is currently a mature library in the kernel. It uses the number
of bytes, PPS and interrupt rate
as samples to make an action, and it is performed independently in tx or
rx direction. Also, There will
be an extra worker to help us send the configuration based on the
control queue to avoid interrupting
the softirq. Although the method of pkt_rate_{low, high} params does not
conflict with dim, I seem
to have some doubts that the colasce parameters of the rx and tx
directions are determined at the
same time based on pkt_rate alone, will this be a problem?
Thanks.
Alvaro
